1. Histidine kinases are expanded in the fusaria.
Histidine kinases are expanded in the fusaria. A phylogenetic tree was constructed for all two-component signaling histidine kinase nucleotide sequences and labeled according to their class (family) (neighbor-joining algorithm). Some kinases were excluded, as they lacked a large portion of the aligned conserved sequence among HisKs. Kinases that are part of the conserved ascomycete kinome (gray background), filamentous kinome (black background), and Fusarium kinome (white background) and kinases that are found only in fusaria in this study (orange background) are indicated. Fusarium oxysporum (Fo) gene identifiers (IDs) are colored red, and Fusarium graminearum (Fg) and Fusarium verticillioides (Fv) gene IDs are colored blue. All bootstrap values above 80% are shown. The domain structure for the class I and class IV HisKs are shown along with a heatmap of the copy number for each class among the fusaria.
